Hollywood and Patient Advocacy – two people who are on our Board but never boring

At first glance Lauren Miller Rogen and Dr. David Higgins seem an unlikely pair. She’s an actor, writer, director and has worked with some of the biggest names in Hollywood. He has a doctorate in molecular biology and genetics and has worked at some of the most well-known companies in biotech. But together they make a great team.

Lauren and David are both on the CIRM Board. She’s a patient advocate for Alzheimer’s and the driving force (with her husband Seth) of HFC (Hilarity for Charity), which has raised millions of dollars to help families battling the disease and to educate young people about the condition. It’s also made a lot of people laugh along the way. David is a patient advocate for Parkinson’s and has been instrumental is creating support groups that help patients and families cope with the disease.

Together they are a force for good. And they’re also really funny. And that’s why we invited them to be guests on the CIRM Podcast, Talking ‘Bout (re)Generation. They are smart, engaging, witty, and they don’t pull punches.

I know you are going to enjoy the show.

Two voices, one message, watch out for predatory stem cell clinics

Last week two new papers came out echoing each other about the dangers of bogus “therapies” being offered by predatory stem cell clinics and the risks they pose to patients.

The first was from the Pew Charitable Trusts entitled: ‘Harms Linked to Unapproved Stem Cell Interventions Highlight Need for Greater FDA Enforcement’ with a subtitle: Unproven regenerative medical products have led to infections, disabilities, and deaths.’

That pretty much says everything you need to know about the report, and in pretty stark terms; need for greater FDA enforcement and infections, disabilities and deaths.

Just two days later, as if in response to the call for greater enforcement, the Food and Drug Administration (FDA) came out with its own paper titled: ‘Important Patient and Consumer Information About Regenerative Medicine Therapies.’ Like the Pew report the FDA’s paper highlighted the dangers of unproven and unapproved “therapies” saying it “has received reports of blindness, tumor formation, infections, and more… due to the use of these unapproved products.”

The FDA runs down a list of diseases and conditions that predatory clinics claim they can cure without any evidence that what they offer is even safe, let alone effective. It says Regenerative Medicine therapies have not been approved for the treatment of:

  • Arthritis, osteoarthritis, rheumatism, hip pain, knee pain or shoulder pain.
  • Blindness or vision loss, autism, chronic pain or fatigue.
  • Neurological conditions like Alzheimer’s and Parkinson’s.
  • Heart disease, lung disease or stroke.

The FDA says it has warned clinics offering these “therapies” to stop or face the risk of legal action, and it warns consumers: “Please know that if you are being charged for these products or offered these products outside of a clinical trial, you are likely being deceived and offered a product illegally.”

It tells consumers if you are offered one of these therapies – often at great personal cost running into the thousands, even tens of thousands of dollars – you should contact the FDA at ocod@fda.hhs.gov.

The Pew report highlights just how dangerous these “therapies” are for patients. They did a deep dive into health records and found that between 2004 and September 2020 there were more than 360 reported cases of patients experiencing serious side effects from a clinic that offered unproven and unapproved stem cell procedures.

Those side effects include 20 deaths as well as serious and even lifelong disabilities such as:

  • Partial or complete blindness (9).
  • Paraplegia (1).
  • Pulmonary embolism (6).
  • Heart attack (5).
  • Tumors, lesions, or other growths (16).
  • Organ damage or failure in several cases that resulted in death.

More than one hundred of the patients identified had to be hospitalized.

The most common type of procedures these patients were given were stem cells taken from their own body and then injected into their eye, spine, hip, shoulder, or knee. The second most common was stem cells from a donor that were then injected.

The Pew report cites the case of one California-based stem cell company that sold products manufactured without proper safety measures, “including a failure to properly screen for communicable diseases such as HIV and hepatitis B and C.” Those products led to at least 13 people being hospitalized due to serious bacterial infection in Texas, Arizona, Kansas, and Florida.

Shocking as these statistics are, the report says this is probably a gross under count of actual harm caused by the bogus clinics. It says the clinics themselves rarely report adverse events and many patients don’t report them either, unless they are so serious that they require medical intervention.

The Pew report concludes by saying the FDA needs more resources so it can more effectively act against these clinics and shut them down when necessary. It says the agency needs to encourage doctors and patients to report any unexpected side effects, saying: “devising effective strategies to collect more real-world evidence of harm can help the agency in its efforts to curb the growth of this unregulated market and ensure that the regenerative medicine field develops into one that clinicians and patients can trust and safely access.”

We completely support both reports and will continue to work with the FDA and anyone else opposed to these predatory clinics. You can read more here about what we have been doing to oppose these clinics, and here is information that will help inform your decision if you are thinking about taking part in a stem cell clinical trial but are not sure if it’s a legitimate one.

Charting a course for the future

A new home for stem cell research?

Have you ever been at a party where someone says “hey, I’ve got a good idea” and then before you know it everyone in the room is adding to it with ideas and suggestions of their own and suddenly you find yourself with 27 pages of notes, all of them really great ideas. No, me neither. At least, not until yesterday when we held the first meeting of our Scientific Strategy Advisory Panel.

This is a group that was set up as part of Proposition 14, the ballot initiative that refunded CIRM last November (thanks again everyone who voted for that). The idea was to create a panel of world class scientists and regulatory experts to help guide and advise our Board on how to advance our mission. It’s a pretty impressive group too. You can see who is on the SSAP here.  

The meeting involved some CIRM grantees talking a little about their work but mostly highlighting problems or obstacles they considered key issues for the future of the field as a whole. And that’s where the ideas and suggestions really started flowing hard and fast.

It started out innocently enough with Dr. Amander Clark of UCLA talking about some of the needs for Discovery or basic research. She advocated for a consortium approach (this quickly became a theme for many other experts) with researchers collaborating and sharing data and findings to help move the field along.

She also called for greater diversity in research, including collecting diverse cell samples at the basic research level, so that if a program advanced to later stages the findings would be relevant to a wide cross section of society rather than just a narrow group.

Dr. Clark also said that as well as supporting research into neurodegenerative diseases, such as Alzheimer’s and Parkinson’s, there needed to be a greater emphasis on neurological conditions such as autism, bipolar disorder and other mental health problems.

(CIRM is already committed to both increasing diversity at all levels of research and expanding mental health research so this was welcome confirmation we are on the right track).

Dr. Mike McCun called for CIRM to take a leadership role in funding fetal tissue research, things the federal government can’t or won’t support, saying this could really help in developing an understanding of prenatal diseases.

Dr. Christine Mummery, President of ISSCR, advocated for support for early embryo research to deepen our understanding of early human development and also help with issues of infertility.

Then the ideas started coming really fast:

  • There’s a need for knowledge networks to share information in real-time not months later after results are published.
  • We need standardization across the field to make it easier to compare study results.
  • We need automation to reduce inconsistency in things like feeding and growing cells, manufacturing cells etc.
  • Equitable access to CRISPR gene-editing treatments, particularly for underserved communities and for rare diseases where big pharmaceutical companies are less likely to invest the money needed to develop a treatment.
  • Do a better job of developing combination therapies – involving stem cells and more traditional medications.

One idea that seemed to generate a lot of enthusiasm – perhaps as much due to the name that Patrik Brundin of the Van Andel Institute gave it – was the creation of a CIRM Hotel California, a place where researchers could go to learn new techniques, to share ideas, to collaborate and maybe take a nice cold drink by the pool (OK, I just made that last bit up to see if you were paying attention).

The meeting was remarkable not just for the flood of ideas, but also for its sense of collegiality.  Peter Marks, the director of the Food and Drug Administration’s Center for Biologics Evaluation and Research (FDA-CBER) captured that sense perfectly when he said the point of everyone working together, collaborating, sharing information and data, is to get these projects over the finish line. The more we work together, the more we will succeed.

U.C. San Diego Scientist Larry Goldstein Joins Stem Cell Agency’s Board

Larry Goldstein, PhD.

Larry Goldstein PhD, has many titles, one of which sums up his career perfectly, “Distinguished Professor”. Dr. Goldstein has distinguished himself on many fronts, making him an ideal addition to the governing Board of the California Institute for Regenerative Medicine (CIRM).

Dr. Goldstein – everyone calls him Larry – is a Cell Biologist, Geneticist and Neuroscientist. He worked with many colleagues to launch the UC San Diego Stem Cell program, the Sanford Consortium for Regenerative Medicine and the Sanford Stem Cell Clinical Center. He has received the Public Service Award from the American Society for Cell Biology and has had a Public Policy Fellowship named for him by the International Society for Stem Cell Research. He is a member of the American Academy of Arts and Sciences and last year was named a member of the prestigious National Academy of Sciences.

“I look forward to working with the ICOC and CIRM staff to ensure that the best and most promising stem cell research and medicine is fostered and funded,” Larry said.

For more than 25 years Larry’s work has targeted the brain and, in particular, Alzheimer’s disease and amyotrophic lateral sclerosis (ALS) better known as Lou Gehrig’s disease.

In 2012 his team was the first to create stem cell models for two different forms of Alzheimer’s, the hereditary and the sporadic forms. This gave researchers a new way of studying the disease, helping them better understand what causes it and looking at new ways of treating it.

He was appointed to the CIRM Board by Pradeep Khosla, the Chancellor of U.C. San Diego saying he is “gratified you are assuming this important role.”

Jonathan Thomas, JD, PhD., Chair of the CIRM Board, welcome the appointment saying “I have known Larry for many years and have nothing but the highest regard for him as a scientist, a leader, and a great champion of stem cell research. He is also an innovative thinker and that will be invaluable to us as we move into a second chapter in the life of CIRM.”

Larry was born in Buffalo, New York and grew up in Thousand Oaks, California. He graduated from UC San Diego with a degree in Biology in 1976 and from the University of Washington with a Ph. D. in Genetics in 1980. He joined the faculty in Cell and Developmental Biology at Harvard University in 1984 where he was promoted to Full Professor with tenure in 1990. He returned to UC San Diego and the Howard Hughes Medical Institute in 1993. After 45 years pursuing cutting edge lab-based research Larry is now transitioning to an administrative and executive role at UC San Diego where he will serve as the Senior Advisor for Stem Cell Research and Policy to the Vice Chancellor of Health Sciences.

He replaces David Brenner who is standing down after completing two terms on the Board.

CIRM funded researchers discover link between Alzheimer’s gene and COVID-19

Dr. Yanhong Shi (left) and Dr. Vaithilingaraja Arumugaswami (right)

All this month we are using our blog and social media to highlight a new chapter in CIRM’s life, thanks to the voters approving Proposition 14. We are looking back at what we have done since we were created in 2004, and also looking forward to the future. Today we focus on groundbreaking CIRM funded research related to COVID-19 that was recently published.

It’s been almost a year since the world started hearing about SARS-CoV-2, the virus that causes COVID-19.  In our minds, the pandemic has felt like an eternity, but scientists are still discovering new things about how the virus works and if genetics might play a role in the severity of the virus.  One population study found that people who have ApoE4, a gene type that has been found to increase the risk of developing Alzheimer’s, had higher rates of severe COVID-19 and hospitalizations.

It is this interesting observation that led to important findings of a study funded by two CIRM awards ($7.4M grant and $250K grant) and conducted by Dr. Yanhong Shi at City of Hope and co-led by Dr. Vaithilingaraja Arumugaswami, a member of the UCLA Broad Stem Cell Research Center.  The team found that the same gene that increases the risk for Alzheimer’s disease can increase the susceptibility and severity of COVID-19.

At the beginning of the study, the team was interested in the connection between SARS-CoV-2 and its effect on the brain.  Due to the fact that patients typically lose their sense of taste and smell, the team theorized that there was an underlying neurological effect of the virus.  

The team first created neurons and astrocytes.  Neurons are cells that function as the basic working unit of the brain and astrocytes provide support to them.  The neurons and astrocytes were generated from induced pluripotent stem cells (iPSCs), which are a kind of stem cell that can become virtually any type of cell and can be created by “reprogramming” the skin cells of patients.  The newly created neurons and astrocytes were then infected with SARS-CoV-2 and it was found that they were susceptible to infection.

Next, the team used iPSCs to create brain organoids, which are 3D models that mimic certain features of the human brain.  They were able to create two different organoid models: one that contained astrocytes and one without them.  They infected both brain organoid types with the virus and discovered that those with astrocytes boosted SARS-CoV-2 infection in the brain model. 

The team then decided to further study the effects of ApoE4 on susceptibility to SARS-CoV-2.  They did this by generating neurons from iPSCs “reprogrammed” from the cells of an Alzheimer’s patient.  Because the iPSCs were derived from an Alzheimer’s patient, they contained ApoE4.  Using gene editing, the team modified some of the ApoE4 iPSCs created so that they contained ApoE3, which is a gene type considered neutral.  The ApoE3 and ApoE4 iPSCs were then used to generate neurons and astrocytes.

The results were astounding.  The ApoE4 neurons and astrocytes both showed a higher susceptibility to SARS-CoV-2 infection in comparison to the ApoE3 neurons and astrocytes.  Moreover, while the virus caused damage to both ApoE3 and ApoE4 neurons, it appeared to have a slightly more severe effect on ApoE4 neurons and a much more severe effect on ApoE4 astrocytes compared to ApoE3 neurons and astrocytes. 

“Our study provides a causal link between the Alzheimer’s disease risk factor ApoE4 and COVID-19 and explains why some (e.g. ApoE4 carriers) but not all COVID-19 patients exhibit neurological manifestations” says Dr. Shi. “Understanding how risk factors for neurodegenerative diseases impact COVID-19 susceptibility and severity will help us to better cope with COVID-19 and its potential long-term effects in different patient populations.”

In the last part of the study, the researchers tested to see if the antiviral drug remdesivir inhibits virus infection in neurons and astrocytes.  They discovered that the drug was able to successfully reduce the viral level in astrocytes and prevent cell death.  For neurons, it was able to rescue them from steadily losing their function and even dying. 

The team says that the next steps to build on their findings is to continue studying the effects of the virus and better understand the role of ApoE4 in the brains of people who have COVID-19.  Many people that developed COVID-19 have recovered, but long-term neurological effects such as severe headaches are still being seen months after. 

“COVID-19 is a complex disease, and we are beginning to understand the risk factors involved in the manifestation of the severe form of the disease” says Dr. Arumugaswami.  “Our cell-based study provides possible explanation to why individuals with Alzheimer’s’ disease are at increased risk of developing COVID-19.”

The full results to this study were published in Cell Stem Cell.

A guide to healing

Dr. Evan Snyder

Having grown up in an era where to find your way around you had to use paper maps, a compass and a knowledge of the stars (OK, I’m not actually that old!) I’m forever grateful to whoever invented the GPS. It’s a lifesaver, and I daresay has also saved more than a few marriages!

Having a way to guide people where they need to be is amazing. Now researchers at Sanford Burnham Prebys Medical Discovery Institute have come up with a similar tool for stem cells. It’s a drug that can help guide stem cells to go where they need to go, to repair damaged tissue and improve the healing process.

In a news release Evan Snyder, MD, PhD, the senior author of the study, explained in wonderfully simply terms what they have done:

“The ability to instruct a stem cell where to go in the body or to a particular region of a given organ is the Holy Grail for regenerative medicine. Now, for the first time ever, we can direct a stem cell to a desired location and focus its therapeutic impact.”

More than a decade ago Snyder and his team discovered that when our body suffers an injury the result is often inflammation and that this then sends out signals for stem cells to come and help repair the damage. This is fine when the problem is a cut or sprain, short term issues in need of a quick fix. But what happens if it’s something more complex, such as a heart attack or stroke where the need is more long term.

In the study, funded in part by CIRM, the team took a molecule, called CXCL12, known to help guide stem cells to damaged tissue, and used it to create a drug called SDV1a. Snyder says this new drug has several key properties.

“Since inflammation can be dangerous, we modified CXCL12 by stripping away the risky bit and maximizing the good bit. Now we have a drug that draws stem cells to a region of pathology, but without creating or worsening unwanted inflammation.”

To test the drug to see how well it worked the team implanted SDV1a and some human brain stem cells into mice with Sandhoff disease, a condition that progressively destroys cells in the brain and spinal cord. They were able to demonstrate that the drug helped the stem cells migrate to where they were needed and to help in repairing the damage. The treated mice had a longer lifespan and better motor function, as well as developing symptoms later than untreated mice.

The team is now testing this drug to see if it has any impact on ALS, also known as Lou Gehrig’s disease. And Snyder says there are other areas where it could prove effective.

“We are optimistic that this drug’s mechanism of action may potentially benefit a variety of neurodegenerative disorders, as well as non-neurological conditions such as heart disease, arthritis and even brain cancer. Interestingly, because CXCL12 and its receptor are implicated in the cytokine storm that characterizes severe COVID-19, some of our insights into how to selectively inhibit inflammation without suppressing other normal processes may be useful in that arena as well.”

CIRM’s President & CEO, Dr. Maria Millan, says this kind of work highlights the important role the stem cell agency plays, in providing long-term support for promising but early stage research.

“Thanks to decades of investment in stem cell science, we are making tremendous progress in our understanding of how these cells work and how they can be harnessed to help reverse injury or disease. Dr. Snyder’s group has identified a drug that could boost the ability of neural stem cells to home to sites of injury and initiate repair. This candidate could help speed the development of stem cell treatments for conditions such as spinal cord injury and Alzheimer’s disease.”

The discovery is published in the Proceedings of the National Academy of Sciences (PNAS)

Exploring tough questions, looking for answers

COVID-19 and social and racial injustice are two of the biggest challenges facing the US right now. This Thursday, October 8th, we are holding a conversation that explores finding answers to both.

The CIRM Alpha Stem Cell Clinic Network Symposium is going to feature presentations about advances in stem cell and regenerative research, highlighting treatments that are already in the clinic and being offered to patients.

But we’re also going to dive a little deeper into the work we support, and use it to discuss two of the most pressing issues of the day.

One of the topics being featured is research into COVID-19. To date CIRM has funded 17 different projects, including three clinical trials. We’ll talk about how these are trying to find ways to help people infected with the virus, seeing if stem cells can help restore function to organs and tissues damaged by the virus, and if we can use stem cells to help develop safe and effective vaccines.

Immediately after that we are going to use COVID-19 as a way of exploring how the people most at risk of being infected and suffering serious consequences, are also the ones most likely to be left out of the research and have most trouble accessing treatments and vaccines.

Study after study highlights how racial and ethnic minorities are underrepresented in clinical trials and disproportionately affected by debilitating diseases. We have a responsibility to change that, to ensure that the underserved are given the same opportunity to take part in clinical trials as other communities.

How do we do that, how do we change a system that has resisted change for so long, how do we overcome the mistrust that has built up in underserved communities following decades of abuse? We’ll be talking about with experts who are on the front lines of this movement.

It promises to be a lively meeting. We’d love to see you there. It’s virtual – of course – it’s open to everyone, and it’s free.

Here’s where you can register and find out more about the Symposium

Meet the people who are changing the future

Kristin MacDonald

Every so often you hear a story and your first reaction is “oh, I have to share this with someone, anyone, everyone.” That’s what happened to me the other day.

I was talking with Kristin MacDonald, an amazing woman, a fierce patient advocate and someone who took part in a CIRM-funded clinical trial to treat retinitis pigmentosa (RP). The disease had destroyed Kristin’s vision and she was hoping the therapy, pioneered by jCyte, would help her. Kristin, being a bit of a pioneer herself, was the first person to test the therapy in the U.S.

Anyway, Kristin was doing a Zoom presentation and wanted to look her best so she asked a friend to come over and do her hair and makeup. The woman she asked, was Rosie Barrero, another patient in that RP clinical trial. Not so very long ago Rosie was legally blind. Now, here she was helping do her friend’s hair and makeup. And doing it beautifully too.

That’s when you know the treatment works. At least for Rosie.

There are many other stories to be heard – from patients and patient advocates, from researchers who develop therapies to the doctors who deliver them. – at our CIRM 2020 Grantee Meeting on next Monday September 14th Tuesday & September 15th.

It’s two full days of presentations and discussions on everything from heart disease and cancer, to COVID-19, Alzheimer’s, Parkinson’s and spina bifida. Here’s a link to the Eventbrite page where you can find out more about the event and also register to be part of it.

Like pretty much everything these days it’s a virtual event so you’ll be able to join in from the comfort of your kitchen, living room, even the backyard.

And it’s free!

You can join us for all two days or just one session on one day. The choice is yours. And feel free to tell your friends or anyone else you think might be interested.

We hope to see you there.

Perseverance: from theory to therapy. Our story over the last year – and a half

Some of the stars of our Annual Report

It’s been a long time coming. Eighteen months to be precise. Which is a peculiarly long time for an Annual Report. The world is certainly a very different place today than when we started, and yet our core mission hasn’t changed at all, except to spring into action to make our own contribution to fighting the coronavirus.

This latest CIRM Annual Reportcovers 2019 through June 30, 2020. Why? Well, as you probably know we are running out of money and could be funding our last new awards by the end of this year. So, we wanted to produce as complete a picture of our achievements as we could – keeping in mind that we might not be around to produce a report next year.

Dr. Catriona Jamieson, UC San Diego physician and researcher

It’s a pretty jam-packed report. It covers everything from the 14 new clinical trials we have funded this year, including three specifically focused on COVID-19. It looks at the extraordinary researchers that we fund and the progress they have made, and the billions of additional dollars our funding has helped leverage for California. But at the heart of it, and at the heart of everything we do, are the patients. They’re the reason we are here. They are the reason we do what we do.

Byron Jenkins, former Naval fighter pilot who battled back from his own fight with multiple myeloma

There are stories of people like Byron Jenkins who almost died from multiple myeloma but is now back leading a full, active life with his family thanks to a CIRM-funded therapy with Poseida. There is Jordan Janz, a young man who once depended on taking 56 pills a day to keep his rare disease, cystinosis, under control but is now hoping a stem cell therapy developed by Dr. Stephanie Cherqui and her team at UC San Diego will make that something of the past.

Jordan Janz and Dr. Stephanie Cherqui

These individuals are remarkable on so many levels, not the least because they were willing to be among the first people ever to try these therapies. They are pioneers in every sense of the word.

Sneha Santosh, former CIRM Bridges student and now a researcher with Novo Nordisk

There is a lot of information in the report, charting the work we have done over the last 18 months. But it’s also a celebration of everyone who made it possible, and our way of saying thank you to the people of California who gave us this incredible honor and opportunity to do this work.

We hope you enjoy it.
